Spherical cobblestone

The spherical cobbles, taken from the sand and stone mountains of the ancient river bed after the crustal movement of tens of millions of years ago, have experienced continuous extrusion and friction during the process of mountain torrents and flowing water. In the course of the evolution of the vicissitudes of thousands of years, the movement of their waves and punching water has lost the irregularities of the rubbing and rubbing of gravel, and silenced in the underground for millions of years. The main chemical components of spherical cobble are silica, followed by a small amount of iron oxide and trace elements such as manganese, copper, aluminum, magnesium and other compounds. They have different pigments, such as red red for iron, blue for copper, purple for manganese, yellow semitransparent as silica gel pulp, jadeite color containing green minerals and so on. So that pebbles appear black, white, yellow, red, dark green, gray and so on.
The use of spherical cobbles:
A decorative ball 1. outdoor laying: Road, Park rockery, potted landscape filling materials. The paved ground and road surface can play a role in beautifying the environment and protecting the body. 2, indoor indoor floor, fish tank and other indoor environment beautification; 3, the building exterior wall decoration suitable for the family bath, hotel lobby and other use, convenient, clear effect, more grade, a return to the nature of the feeling of two industrial stone: natural gravel filter is a large number of artificial selection, with the strength of quartzite It can be used to filter the living water, industrial water, industrial wastewater and domestic sewage. It has a good filtering effect on the turbidity in the water, and can be used as a bearing layer according to various particle sizes.
On the distribution of spherical cobbles:
The major spherical cobblestones in China are from the Lingshou area of Hebei. The front areas of the Taihang Mountains are rich in resources and many are deposited. In addition, the pebble resources in the rest of the region are also abundant, and the pebble resources in the North including Shijiazhuang and Lingshou have their own characteristics, and the species are rich and rich in variety. Among them, Shijiazhuang and Lingshou's Pebble resources are relatively well preserved because of historical reasons. There are many large pebbles in the southwest, which are large and odd in shape. They are especially suitable for geomantic stones or cultural stones of landmark buildings.
